Table 1 Parameters used in the model
From: Incorporating and addressing testing bias within estimates of epidemic dynamics for SARS-CoV-2
Parameter | Meaning | Value | Source | Notes on calculation from data source |
|---|---|---|---|---|
β | Transmission rate | \( 1.12\times \frac{3.47}{3.47+3.69}\ {\mathrm{days}}^{-1}=0.543\ {\mathrm{days}}^{-1} \) | Li et al. [29] | Calculalated by weighting the transmission rate by the latency and infectious periods |
γ | Disease recovery or resolution rate | \( \frac{1}{\left(3.69+3.47\right)\ \mathrm{days}}=\frac{1}{7.16\ \mathrm{days}} \) | Li et al. [29] | Summing up the latency and infectious period |
q | Fraction of infected individuals who are symptomatic (or with more severe disease) | 0.15 | Li et al. [29] | about 86% were undocumented infected |
f | Fatality rate for individuals with severe/symptomatic disease | 0.02 | – | Nominal value for illustrative purposes |
